Everest account

I took a quiz in pokerstrategy and choosed Everest for the platform. I created the account, and everything was ok. When I closed the Everest program, and re-opened it, it told that the username or password was wrong. I used "Forgot username" link, and it said that my username was sent to my e-mail. Have done it already for 5 times but no e-mail received, what's happening?
I know that the username/password weren't also wrong.
